The Regression Coefficients II

With both smile and money in your model, you found that the slope coefficient for money is 0.8008, smile is 1.4895 and the intercept is 0.6162. How is this different from predicting liking with only smile or only money?

In your console, look at the coefficients for a model with only smile by entering lm(liking ~ smile) and only money by entering lm(liking ~ money). Compare the change in coefficients from the model with two predictors, to the model with one predictor and select the correct statment from below.
